Computer software
Computer Software
Computer software (pronounced /ˈkɒmpjʊtər ˈsɒftwɛər/), also known as software, is a collection of data or computer instructions that tell the computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work.
Etymology
The term "software" was first proposed by Alan Turing and used in this sense by John W. Tukey in 1957. In computer science and software engineering, computer software is all information processed by computer systems, programs and data.
Types of Software
Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.
System Software
System software directly operates the computer hardware, to provide basic functionality needed by users and other software, and to provide a platform for running application software.
Application Software
Application software, also known as an "application" or an "app", is a computer software designed to help the user to perform specific tasks.
